Replace it with the following block, between the {php} and {/php}
$link = mysqli_connect(localhost,EZSQL_DB_USER,EZSQL_DB_PASSWORD);
/* check connection */
if (mysqli_connect_errno()) {
printf("Connect failed: %sn", mysqli_connect_error());
exit();
}
$my_sql = mysqli_get_server_info($link);
//$my_sql returns will be something like the version and -log (5.5.24-log). we have to just grab the version number
$my_sql_version = substr($my_sql, 0, strpos($my_sql, "-"));
echo $my_sql_version;
mysqli_close($link);
